The men in Sendai Station [the capital of Miyagi prefecture] are potential laborers that Sasa can dispatch to contractors in Japan's nuclear disaster zone for a bounty of $100 a head.

"This is how labor recruiters like me come in every day," Sasa says, as he strides past men sleeping on cardboard and clutching at their coats against the early winter cold.

It's also how Japan finds people willing to accept minimum wage for one of the most undesirable jobs in the industrialized world: working on the $35 billion, taxpayer-funded effort to clean up radioactive fallout across an area of northern Japan larger than Hong Kong...

In January, October and November, Japanese gangsters were arrested on charges of infiltrating construction giant Obayashi Corp's network of decontamination subcontractors and illegally sending workers to the government-funded project.

In the October case, homeless men were rounded up at Sendai's train station by Sasa, then put to work clearing radioactive soil and debris in Fukushima City for less than minimum wage, according to police and accounts of those involved. The men reported up through a chain of three other companies to Obayashi, Japan's second-largest construction company.

Obayashi, which is one of more than 20 major contractors involved in government-funded radiation removal projects, has not been accused of any wrongdoing. But the spate of arrests has shown that members of Japan's three largest criminal syndicates - Yamaguchi-gumi, Sumiyoshi-kai and Inagawa-kai - had set up black-market recruiting agencies under Obayashi...

Japan has always had a gray market of day labor centered in Tokyo and Osaka. A small army of day laborers was employed to build the stadiums and parks for the 1964 Olympics in Tokyo. But over the past year, Sendai, the biggest city in the disaster zone, has emerged as a hiring hub for homeless men. Many work clearing rubble left behind by the 2011 tsunami and cleaning up radioactive hotspots by removing topsoil, cutting grass and scrubbing down houses around the destroyed nuclear plant, workers and city officials say...

"If you don't get involved (with gangs), you're not going to get enough workers," said Sayama, Fujisai's general manager. "The construction industry is 90 percent run by gangs."

...Nishiyama's first employer in Sendai offered him $90 a day for his first job clearing tsunami debris. But he was made to pay as much as $50 a day for food and lodging. He also was not paid on the days he was unable to work. On those days, though, he would still be charged for room and board. He decided he was better off living on the street than going into debt.

In the titanic struggle to bring to closure the dangerous situation at Fukushima Nuclear Plant No1, there are many signs that TEPCO is facing great difficulties in finding workers. At present, there are nearly 700 people at the site. As in ordinary times, workers rotate so as to limit the cumulative dose of radiation inherent in maintenance and cleanup work at the nuclear site...

But this time, the risks are greater, and the method of recruitment unusual.

Job offers come not from TEPCO but from Mizukami Kogyo, a company whose business is construction and cleaning maintenance. The description indicates only that the work is at a nuclear plant in Fukushima Prefecture. The job is specified as 3 hours per day at an hourly wage of 10,000 yen. There is no information about danger, only the suggestion to ask the employer for further details on food, lodging, transportation and insurance.

Those who answer these offers may have little awareness of the dangers and they are likely to have few other job opportunities. $122 an hour is hardly a king’s ransom given the risk of cancer from high radiation levels. But TEPCO and NISA keep diffusing their usual propaganda to minimize the radiation risks.

Rumor has it that many of the cleanup workers are burakumin. This cannot be verified, but it would be congruent with the logic of the nuclear industry and the difficult job situation of day laborers. Because of ostracism, some burakumin are also involved with yakuza. Therefore, it would not be surprising that yakuza-burakumin recruit other burakumin to go to Fukushima. Yakuza are active in recruiting day laborers of the yoseba: Sanya in Tokyo, Kotobukicho in Yokohama, and Kamagasaki in Osaka. People who live in precarious conditions are then exposed to high levels of radiation, doing the most dirty and dangerous jobs in the nuclear plants, then are sent back to the yoseba. Those who fall ill will not even appear in the statistics.

Many prefer to turn a blind eye as it is reassuring to believe TEPCO’s nonsense and the nostrums provided by scholars associated with the nuclear lobby. But there is also a growing awareness of the problem, which can be observed for example through the vast mobilization in the region of Fukushima and Tokyo among citizens and on the Internet...

Temporary subcontract workers who have never entered a nuclear plant before probably have a very vague perception of these risks.

Public bids are now almost entirely controlled by the construction companies at the top (moto uke) and the yakuza at the bottom;

Though the Ministry of the Environment only authorizes two levels of subcontracting, in practice, the levels of subcontracting are even more numerous than at F1 and other nuclear plants. Between his own employer and Shimizu Construction, the moto uke, Masato has counted 24 levels;

Wage skimming is the norm and many workers only get a tiny portion—if any—of the 10,000 Yen hazard allowance;

The majority of workers receive no health insurance benefits from their employer and for many reasons they do not register for the national health insurance system on an individual basis.
